I've read through all the otherwise wonderful advice on this thread, and there seems to be one area that we've all overlooked, and which in hindsight I wish I started thinking about earlier.
We don't like to think about our profession as one that has moral responsibility for the things that we create. Morality is a squishy concept, ever shifting and difficult to pin down, but with software playing an ever bigger part in our society, we simply can't avoid that discussion.
I'm not going to pontificate about what's right and what isn't, not least of all because I don't know either, but I'm sure it's important, and we must start thinking about it as early in our careers as possible.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
